7 Claims.

This invention relates to valves in general and more especially to valves or closures for collapsible tubes, such as today are extensively used for carrying shaving cream, tooth paste, paint and the like.

Among the objects of the present invention, it is aimed to provide an improved non-removable closure or valve having a collapsible tube which will produce not only an effective air-tight moistureproof closure but also a neat closure without the untidy extrusion so commonly accompanying the closing of non-removable closures.

These and other features, capabilities and advantages of the present invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawing in which Figure lis a fragmental side eleva-tion of a tube equipped with a closure constituting the present invention in closed position;

Fig. 2 is a plan of the valve in closed position;

Fig. 3 is a fragmental section on the line 3-3 of Fig. 1;

Fig. 4 is a fragmental side elevation of a tube equipped with the closure constituting the present invention in open position;

Fig. 5 is a plan of the valve in open position;

Fig. 6 is a fragmental section on the line 6--6 of Fig. 4;

Fig. 7 is a side elevation of the valve removed from the tube looking at a wide curved side thereof;

Fig. 8 is a plan of the valve removed from the tube;

Fig. 9 is a side elevation of the valve removed from the tube looking at a narrow side thereof; and

Fig, 10 is a fragmental section of the tube with the valve removed along the line lIB-I of Fig. 4,

In the embodiment shown, there is illustrated a conventional collapsible tube body I having a narrow neck 2. The neck 2 has an inwardly extending internal thread 3 and an opening 4 formed in the outer end of the neck 2.

The opening 4 has a semi-circular outer edge 5 in plan view, see Figs. 2 and 5 and an inner interrupted edge having a short radial portion 6 and a downwardly curved portion 'I separated from the radial portion 6 by a shoulder 8, which shoulder 8 is disposed substantially at the axial center of the neck 2 from the interrupted edge formed by the portions 6 and l. The neck portion 2 is provided with an inclined conical wall II) forming a continuation of the cylindrical wall II of the neck 2. 'I'he thread 3, see particularly lvalve seat tube.

(Cl. 221-) 5,.: Figs. 1, 3 and 6, extends substantially parallel withthe outer curved edge 5 of the opening 4. In other words, the curved edge 5 is also spiral in conformation, the flange or shoulder I2 formed on the outer end of the neck 2 adjacent to the curved edge 5 cooperating with the thread 3 to form an internal spiral valve seat portion along such edge 5, The inside of the neck 2 is, in the present instance, provided with a shoulder I3 formed at the outer end of the thread 3.

Adjacent the edge 3, the portion I4 of the neck I I is slightly curled inwardly to form a protective ange cooperating with the wall I ll and flange I2 to complete the valve seat of the valve now to be described.

The valve I6 now to be described, see particularly Figs. 7, 8 and 9 has a thread I'I for cooperation with the thread 3, a washer receiving recess for receiving the washer I8 which has asemi-circular spiral portion I9, see Fig. 8, conforming tof2o the seat portion formed by the semi-circular spiral flange I2. 'I'he washer and recess also have an irregular connecting portion consisting of the elements 20 and 2I conforming to the seat portions formed by the shoulder I4 and tapered 'l wall I0 respectively.

The valve I6 also preferably has a stem 22 extending inwardly to facilitate gripping the valve by a tool during the process of assembling the also serving as a stop for limiting the opening movement of the' same and in turn for anchoring the valve to the tube in non-removable position after having been once assembled. 'I'here is provided in the present instance the handle 23 which preferably extends upwardly from the outer face 24 of the valve adjacent to the washer Aportion 20. This handle 23 may be of any one of several suitable conformations, as an instance, the hook form illustrated.

In the process of assembling, the stem 22 of the valve I6 is preferably gripped by a tool or the like before the handle 23 is secured in place and thereupon the tube I passed over the valve and manipulated until the threads 3 and II engage. Thereupon, the tube I and valve I 6 are preferably turned relative to one another until the valve is in closed position and then the handle 23 is secured in position on the valve I5 preferably to extend from the surface 24 adjacent to the washer portion 20 as indicated in Figs. 5 and 8.

From the foregoing, it will appear that particularly as distinguished from the disclosure in Patent No. 2,067,917, the valve is turned to move outwardly into closed position, whereas in the For operating the valve I6 and isp aforesaid patent, the valve is moved inwardly into closed position. By this diierence, certain decided advantages result. As an instance,when the valve is turned outwardly into closed position, it tends to create a vacuum within the body l thereby tending to suck the substance surrounding the valve seat into the body and thereby eiectively removing the same from the outlet. When the valve moves inwardly into closed position, on, the other hand, pressureis created Within the body and there isa tendency to extrude a small increment at the nal closing movement resulting in an untidy closure in closed position. Of

Y course, advantage is here still taken of the effec- 'opening -without'requiring'an additional stop element.

It fis fobvious that various `changes and modifications may be made in the details ofconstruc- =tion Awithout 'departing from lthe general spirit 4of the invention vas set forth in the appended claims.
